A handout image of a CT scan of the front half of a lower jaw bone of a saber-toothed mammal-like beast that prowled Tanzania 255 million years ago. Bone is shown in red and teeth are in blue. Importantly, this is not the specimen in which the odontoma was found; it is included as a representative of what gorgonopsian jaws and teeth look like.
